To Calculate price
per Lineal metre from price per m^{ 3}:

Enter price per m^{ 3} |
x T (in m) x W
(in m) |
= price per lineal

Sheet materials

2440 x 1220 mm sheet
(metric 8' x 4') = 2.9768 m^{ 2}

3.3593 sheets = 10 m^{ 2}

To calculate price
per sheet from price per 10m^{ 2} (for
2440 x 1220)

Enter price per 10 m^{ 2} |
÷ 3.3593 | = price per sheet |

For hardwood sawlogs and veneer logs (and occasionally for softwood sawlogs) some roundwood merchants, sawmillers and contractors continue to use imperial units in which volume is expressed in hoppus feet (hft), derived as follows: |

Hoppus Volume = | (Mid Quarter Girth in ins.)^{2} | X | Length (ft) |

(hft) | |||

144 | |||

The girth tape used is calibrated in quarter girth (QG) in inches, and the cross-sectional area is approximated by squaring the QG and dividing by 144. One Hoppus foot = 1.273 true ft |

1 cm diameter = 0.31 ins. QG; |
